Link commands in gdb to observe the execution stack

Question

I am looking for a program to observe the execution stack of a c/c++ program. Currently I am using gdb for this purpose.

The following command shows the content of the stack:

x/12xg $rsp

to execute instruction after instruction I am using

stepi

Is it possible to combine these to commands so that I would be able to stept through the assembly code and observing the stack? If you have another possible solution/program I am looking forward to hear that as well.

It may depend on what you want to do ("why?"). You could set breakpoints at function entries, you could use print statements to get your information, etc. — Paul Ogilvie

You can use display in gdb, or even automate it so that it steps through your whole program. — Jester

You can combine commands using define, like:

(gdb) define mystep
> stepi
> x/whatever $rsp
> end

Now mystep should step and then dump some memory.
